Designed with couples in mind, The Cube has everything that a family of two could want. Ample storage space and seating, a full kitchen and bathroom, a lounge, and a washing machine make up the long list of amenities included in this tiny home. The best part, however, is its low environmental impact. The Cube is built with sustainable materials, has a composting toilet, and uses low-energy electronics to ensure a carbon footprint even smaller than the house itself.
